Predicted to enable ferric iron binding activity; ferrous iron binding activity; and identical protein binding activity. Involved in response to lead ion. Located in cytoplasm. Human ortholog(s) of this gene implicated in basal ganglia disease; hyperferritinemia-cataract syndrome; neurodegeneration with brain iron accumulation 3; and neurodegenerative disease. Orthologous to human FTL (ferritin light chain). [provided by Alliance of Genome Resources, Apr 2022]
